FIELD: oil and gas industry.
SUBSTANCE: group of inventions is related to drilling techniques using a high-power laser. The high-power laser drilling system used together with a drilling rig, a drilling platform, a drill derrick, a string snubbing platform or a drilling rig with a flexible string piping for hole-making in solid rock contains a high-power laser generator capable of generating a laser beam with power of at least 20 kW, a bottomhole assembly equipped with an optic unit capable to generate the preset energy deposition profile for the wellbore surface and the preset laser spots pattern, a unit for running-in the bottomhole assembly to the wellbore and movement inside it when the wellbore is moved downwards, a cable for delivery the high-power laser beam with a length of at least about 1000 feet (305m) coupled optically to the generator and the bottomhole assembly.
EFFECT: higher efficiency in drilling of deep wells.
